I think I had it running with 1.0.10rc1 on both driver and tools, but Im not
completely sure about alsa-driver anymore.

I have now tested again with both at 1.0.10rc2, everything compiled 64bit.

init_live still creates a setup with heavily distorted output, but when cleaning
the DSP setup with qlo10k1 and setting up a single master volume control slider
and routing from PCM to different speakers, I have been able to change their
volume successfully afterwards - so most of the backend seems to be working.

Maybe specific patches have problems, or the init_live scrip doesnt fit my card,
I'll give it some further tests, trying to find a working routing with adequate
mixer controls. Thanks for answer :-)
